Bring the water to a boil and add the oatmeal slowly, stirring as you add it. Reduce heat to a simmer and let the oatmeal cook for 3 minutes or until it is thick. Remove from heat and add the pumpkin puree. Stir until well blended. Add the sucanat and stir well. Add the pumpkin pie spice and extra cinnamon if desired. Taste it first. Add milk if desired to make it creamier, or eat it as is.
